Rational Equations 01

Section 8.6     ....      SOLVING RATIONAL EQUATIONS (page 542)

First multiply each side by the least common denominator (LCD) of the rational expressions. Doing this, however, can introduce extraneous solutions. A rational equation contains at least one rational expression. Recall that an extraneous solution is a solution of the derived equation, but not a solution of the original equation. You must check all solutions in the original equation to confirm that they are indeed solutions.
